3 Claims. (Cl. 292-276) This invention relates to devices for fastening windows, doors, and the like.

An object of the invention is to provide a fastening device for windows and doors, which is so arranged as to be opened with difiiculty by an intruder, yet which is quite simple to open by one who is not an intruder.

Another object of the invention is to provide awindow and door fastening device which is so constructed that it is easy to be manipulated by those who are not strong, such as women and children.

Still another object of the invention is to provide a device whereby windows and doors may either be locked in closed position, or in partly open position, the device having the external appearance of a tamper-proof lock, and having operating parts the working of which is not readily apparent from casual inspection thereof by an intruder, the lock being provided with a plunger rod which is secured in place by a threaded member that cannot be turned out of position without employing a special form of wrench, so as to confuse and bewilder an intruder.

A further object of the invention is to provide a lock which is simple in design, inexpensive to manufacture, and effective for the purpose intended. 1

Other objects and advantages of the invention will become apparent from the following description of a preferred embodiment thereof as illustrated in the accompanying drawings, and in which,

Figure 1 is a top plan view of my improved fastening device in position upon two window sections showing them in locked position.

Figure 2 is a'front elevational view of the devices shown in Figure 1, but with the window sections'partly ajar and the lock holding them in such engagement.

Figure 3 is a sectional view taken on line 33 of Figure 2, and showing only the lock.

Figure 4 is a sectional view taken on line 4-4 of Figure 2, showing only the lock.

Figure 5 is a side elevational view of a portion of a modified form of the locking device shown in Figures 1 and 2, and

Figure 6 is a perspective view of the lock mounting bracket of Figure 5, shown apart from "thelocking device.

throughout the several views.

As shown, there are two windows Ill and 12 which in Figure 1 are shown in closed position, while in Figure 2 they are shown in partly open position, their abutting edges l 4: and I6 being slightly separated to allow passage of air therebetween for ventilating a room or the like. The windows are hinged to a window frame at their opposite edges,.not shown, in any usual manner well known in the art. J 1

The present invention provides means for securing the, two windows together in closed position, as shown in Figure 1, or in the open position shown in Figure 2, entrance of an intruder being blocked in both cases by the locking means illustrated. The lock includes a first major housing block 18 which may be formed in any suitable manner such as by machining or casting, having a base portion 26 having 'upper'and lower extensions 22 and 24 as seen in Figure 2. The outer surfaces 26 of the extensions Hand 24 lie in a plane which is inclined toward the plane of the inner surface 28 of the base, as best shown in Figures 1 and 3, the inner surface being adapted for abutting against the surface 3|! of the door It.

The extensions 22 and 24 are provided with bores 32 for the reception of fastening screws 34 which are threaded into matching holes formed in the door l0. As seen best in Figure 3, the axes of the screw bores 32 are perpendicular to the plane 28 and to the face of the door 10, being countersunk at their outer ends to receive the screw heads below the surfaces 26 of the base extensions. The housing block 18 has an upraised portion 36 integral with the base 20, and having longitudinal bore 38 extending therethrough, as best shown in Figure 3, the axis'of the bore lying in a plane parallel to the plane of the surfaces 26 of the base, and adapted to receive a connecting rod 40.

A second bore 42 is formed in the upraised portion 36 of the housing block l8, the second bore extending inwardly from the upper surface 44 thereof and intersecting the bore 38, the axis of the second bore being substantially perpendicular to that of the first bore 38. The second bore 42 is threaded to receive a correspondingly threaded fastening plunger 46 the/inner end of which is conical as shown in Figure 3, to present a pointed extremity for engagement against the contiguous surface of the connecting rod 40, the pointed end being adapted for slightly penetrating the connecting rod to hold it securely against being withdrawn from the bore 38;

"Ihefastening plunger 46 has upstanding stubs or proiections50 on its outer surface, as seen best in Figure 3, for reception in corresponding sockets or recesses 52 formed in the inner end of a key or wrench 54 the shank 56 of which is adapted to enter the unfilled end of the second bore 42 so as to engage the projections 50 and thus the fastening plunger 46. When this is done, the head of the wrench or key 54 may be turned about its axis, either to turn the plunger 46 tightly againsttheconnecting rod 40, or to disengage it therefromysoas 'to permit the rod to be withdrawn from the bore 38.

The other end of the connecting rod 4|] extends into the slot 58 of bifurcated end 60 of :theshaftsecond major housing block :68, being secured against withdrawal axially from the recess 66 by means of a pin which extends through the base 12 of the block 68 and into an annular groove 14 formed intheshaftiBZ. The base 72 has its innerand 'outer'surfaces (6;and :18 lying in in- .tersecting :planes, as best shown in Figures 1 and-4, .the inner surface 16 beingadapted to lie against the face surface to of "the window [2. Bores.82 are formed in the base P2 of the block 68', to:receive fastening screws or bolts 84 the lower ends ;of which engage :in the window l2'to hold the block 68 securely thereon.

In operation,:when the windows are to be moved from theipartlyopenposition of Figure 2 to the closed position of Figure 1,.it is only necessaryi'to turn the-wrench "54 so as .to disengage the set screw 46 from the rod 40, and then close the windows the rod 40 sliding to the positionshown v desired, to-form a tighter joint when engaged by theset screw. When the windows are-completely opened, wholly withdrawing the rod 40 from the bore 38, it may be'turned with the clevis 60,50 as to hang down in a verticalplane, thus'being-out of-the way;

As shown in Figure 5, the left hand majorblock 18A may be formed with a flatinstead of wedgeshapedbas'e, being otherwise similar to the block l8shown in Figures 1, 2 and 3, and provided with a fastening angle memberBZ which is shown in perspective in Figure 6. The upper leg 84 is secured to the flatbase of the block ISA'by means of screws 86 extending through slots 88 therein, thus providing lateral adjustment of position. The lower leg 99 of the angle memberhas holes for'the reception of screws by means of which it maybesecured to a door or-other member.

It will be seen that the device as herein described provides a-means for securing windows and the likein closed, or partly open positions without permitting entry of an intruder; The key.54 is notnormally left in position, and the intruder cannot reach the set screw 46. And if'he shouldbe able toreach it, he cannot turn it out without having a key with the same combination or arrangement of recesses 52 corresponding to thenurnber and arrangement of the projections 50.

The-ensuing hesitation and confusion on the .part of the intruder will usually cause him to defer attempting entry, and probably block the-attempt altogether. 1 Although I have described a preferred embodiment of my invention in specific terms, it is to be understood that various changes may bemade in size, shape, --material and arrangement with,-

out departing from the spirit and scope of the invention as claimed.
